Definitions

  • the present invention relates to biocidal agents with excellent fungicidal and algicidal action, consisting at least of an algicide, propiconazole and an iodopropargyl compound, where preferably at least one of the active ingredients is bound, preferably microencapsulated.
  • Biocidal agents which comprise propiconazole and IPBC are already known from the literature. Such agents are sold for example under the trade name Preventol A 12-TK 20 by Lanxess GmbH in the form of an emulsion concentrate with about 10% by weight IPBC and about 10% by weight propiconazole.
  • JP 2010-126456A discloses active ingredient combinations of algicides and IPBC as wood preservatives.
  • JP 2011-121901 A discloses wood preservatives which comprise triazole compounds and urea compounds, such as for example propiconazole and diuron.
  • the long-term action in the technical materials to be protected such as in particular paints or plasters is not sufficiently good because the biocides are dissolved out of the materials particularly in the exterior sector for example by precipitated water or condensed water.
  • the so-called “leaching” leads to a concentration drop of the biocides, which over time leads to a reduction in the biocidal action to the point of loss of action.
  • the precipitated water or condensed water laden with biocides can enter the environment, particularly ground water, and leads to undesired contamination.
  • the general aim is to slow the leaching to such an extent that the released amount of biocides is so low that no unnecessary environmental impact arises, but the amount at the same time suffices to suppress the growth of undesired microorganisms.
  • the prior an discloses a large number of methods with the help of which the leaching behavior is improved and the release of the biocides is slowed by means of encapsulation, adsorption onto solid supports or inclusion in a polymer matrix.
  • active ingredients that are encapsulated, adsorbed to solid supports or bound in a polymer matrix used in contrast to the free active ingredient in the context of a slowed release are also referred to hereinbelow as bound active ingredients.
  • Triggered release is initiated through changes in the capsule sheath. These changes can be brought about by chemical, biological, magnetic, electronic stimuli or by light.
  • Controlled release mostly takes place in a diffusion-controlled manner.
  • the literature discloses a large number of systems with diffusion-controlled release. These include polymeric nanoparticles, microspheres, porous silica microparticles, inorganic silica structures, sol-gel matrices and modified nanoclays.
  • An in often used capsule material is melamine-formaldehyde resins.
  • melamine-formaldehyde resins For example, it is known from WO 2004/000953 A to incorporate biocides into microcapsules with wall materials made of specific formaldehyde-melanine resins in order to be able to use them in coating materials which have a pH of more than 11.
  • EP 0 758 633 A describes porous granules which comprise chemical substances, such as e.g. also biocides, and which slowly release them during use.
  • microcapsules have become known which preferably comprise zinc pyrithione or Irgarol and which are produced by freeing aqueous dispersions of polymer solution, active ingredient and low-boiling solvent from the solvent with vigorous stirring and isolating the resulting microcapsules by filtration (see US 2006/0246144).
  • coacervation Another method of producing “slow release formulations” is coacervation. It is often used for the encapsulation of liquid or solid active ingredients in suspension or emulsion. A distinction is made between simple and complex coacervation. The underlying physical and chemical processes during these two encapsulation methods are well understood and described in detail in the literature. The patent literature describes both the method of complex coacervation (cf. e.g. GB-A 1475229 and U.S. Pat. No. 2,800,458) as well as that of simple coacervation (cf. e.g. GB-A 1275712).
  • a common feature of these methods is that either the solid or dissolved active ingredient is surrounded (encapsulated) with an encapsulation material, the active ingredient is bound to a support by adsorption or solutions of the active ingredient are evaporated with polymers such that the active ingredient is then present as a core surrounded by a polymer wall in the form of fine beads.
  • a further way of suppressing the leaching of active ingredients is homogeneous distribution of the active ingredient within a polymer matrix.
  • biocide-containing, thermoplastic polymer particles to be obtained by extrusion and grinding are described in WO 2009/00650 A.
  • bound active ingredients is understood as meaning active ingredients or mixtures of active ingredients which are

  • a polymer matrix means particles, preferably monolithic particles, in which the active ingredient is homogeneously distributed in at least one thermoplastic polymer. “Homogeneously distributed” is also understood as meaning the distribution of an active ingredient introduced after mixing and extrusion into the at least one thermoplastic polymer.
